What Does Follow The Sun Mean When Painting Outdoors?

Exterior painting projects nowadays a variety of challenges, ranging from the type of project and surface to be painted, to geographic location and the spectrum of diverse, outdoor conditions across the Southwest. Despite all these factors, we demand that our congenital environs exist protected past a flick that is only a ane-thousandth of an inch thick — so how do nosotros ensure skillful exterior pigment performance, especially when applying paint in summer heat? Hither are some things to consider:

Start, the cardinal to any skillful paint task is always surface training. Wash the surface to remove loose dirt and grit. Next, scrape and sand surfaces to remove loose, peeling and flaking paint. Continue in mind that scraping or sanding surfaces of older buildings (especially pre-1978) may release dust containing pb or asbestos.* One time the surface is clean, prime any exposed substrates with the advisable primer.

Next, choose the right paint for the job. Today'due south 100 percent-acrylic paint systems offering the all-time performance on a variety of surfaces; however, not all acrylic paint resins perform the same. Be sure to check for pigment performance properties (due east.k., adhesion, flexibility, color fade, gloss loss). So, bank check the production'due south volume solids, as this is an indicator of the amount of resin and paint in the paint. A lower percentage
ways less resin and paint, which tin can result in lower performance. Last, only expect at the toll. A lower toll can indicate inferior performance. Remember: You get what y'all pay for!

Also, consider how colour tin affect paint performance. Darker colors absorb more heat and energy, which cause substrate motion that can shatter the bail between previous coats and the substrate — especially
forest. Using lighter colors is beneficial, as they reflect more than light and practise not blot every bit much heat and energy; thus, improving moving-picture show durability. The fact that lighter colors do not absorb every bit much heat also suggests that lighter colors can better energy efficiency. A good indicator of how well a colour reflects light is to await at its Light Reflectance Value or LRV. Higher values (closer to 100) indicate colors that reflect more low-cal.

In improver, here are some things to consider when applying paint in the summer oestrus:

When painting in warm conditions, a latex pigment is forced to dry very quickly. When this happens, the pigment tin be dry but motion-picture show formation or curing may be incomplete, which will compromise long-term durability.

When painting exteriors, it's best to avert having more than two or three of the following atmospheric condition present
simultaneously:

Painting under very hot conditions, above 95º F
Painting in straight sunlight, especially if the paint is a dark color
The surface being painted is hot
The surface is very porous
Conditions are breezy or windy

One of the best ways to endeavor and stay within these guidelines is a technique called, "chasing-the-shade." Starting time applying paint on the shady side of a building and follow the shade as the sun moves overhead. Some other style to minimize the effects of summer estrus is to paint early in the morning when it is cooler. If anything, try to avert painting in the late afternoon when surfaces have had a run a risk to oestrus up and it becomes too hot to use paint. Last, proceed your brushes and rollers loaded with paint; work in smaller areas; and apply pigment at a consequent, steady stride to get a good, uniform finish.
